To all whom t may concern:

Be it known that I, JOY s. Emisoras, 'citi'- zen of the United States, residing at Seattle,-

in the countyl of King and State of Washington, have invented a certain new and useful Improvement in Gas-Burners, of which the following is a specification.

My invention relates to improvements in gas burners, and the object of my invention 1s to provide a portable gas burner which shall be so constructed that it shall be adapted to conduct and deliver to a focal polnt line 6, 6 of Figs.

of combustion a plurality of jets of a combustible mixture of gases and a singlejet .of oxygen, or steam, or air, at which point of combustion said combustible mixture of gases and said oxygen or said steam or said air will be intermingled and there to be ignited to produce a flame of extremely high temperature, and which ame, by a manipulation of the burner, may be directed to 1mpinge upon the surfaces to be heated. A further object of my invention is to provide a burner wherein its tubular body portion is formed of one piece of metal through which is provided a passageway for gas extending from the inlet end tothe outlet end thereof whereby there will be nol joints formed in aidk. passageway through which gases may I accomplish these objects by devices illustrate'd in the accompanying drawings, wherein- Figure 1 is a view in longitudinal midsection of the operative parts of a burner embodying my invention:

Fig. 2 is a view of the same in crosssection on broken line 2, 2 of Fig. 1;

Fig. 3 is a view of the same in crosssection on broken line 3, 3 of Fig. 1;

Fig. 4 is a view in longitudinal mid-section of a modified form of burner embodying my invention; f

Fig. 5 is a like view of saidl modified form of burner, which shows a different arrangement of parts thereof; k v

Fig. 6 is azview in cross-section on broken 4 and 5:, and Fig. 'I 's a view in cross-section on broken line 7, 7 of said Fig. 5.

v Referring to the drawings, throughout which like referencenumerals indicate like parts', as shown in Fig.'1, a tubular body is formed to have a portion 4, preferably of hexagonal cross-section. a portion 5 of smaller diameter 'whereby is formed an annular shoulder 6 from which projects an annular bead'?, a portion 8 of still smaller diameter, an externally screw-threaded portion '9, a portion 10 of still smaller diameter,

and a tapered portion 11 whose inner end portion is surrounded by an integral collar 12.

Extending through verging lines its -inner side outer side, are a plurality of minute apertures 13, the focal point of said converging the collar 12 in confrom the annular surface of Patented Dec. l10, 1918.

to the annular surface'of its 1 lines being at a distance from the outer annular surface of said outer side, andthe constricted outlet end 14 of the passageway 15 through the tubular body being concen-d tric with the collar 12 whereby a jet of gas 'emitted from said passageway A15 will be directed in a straight line to said focal point there w mix with the converging jets of va mixture of gases that are emitted from the' several apertures 13.v v

` The passageway 15 in'the rearward end of the portion 4 is closed by a plugf16.

Extending in a sidewise direction from one side of the portion Lfis an integral externally screw-threaded nipplev 17 through which is a passageway 18 that connects with the rearward'end portion of the passageway 15.

Connected by a union 19 to the nipple 17 is a conduit pipe 20 that may be extended to -a source of oxygen gas or other suitable gas under pressure.

A hexagonal ond closely fitting the portion 5' and with its rearward annular surface in airtight engagement with the annular b ead 7. whereby is provided an annular space 22 `between the cylindrical surface of the portion 8 and the said sleeve 23 90 sleeve 21 is disposed to sur-f .round the portions 5 and 8 with its rearward portion 24 within .which is an inwardly projecting screw-threaded ange 25 whose screw thread operatively engages with the screwthread of the .portion 9 thereby to force the rearward end of said sleeve 23 against the adjacent end surface of the sleeve 21.

Extending through said flange 25,`flrom" nozzle 33 in the i the acetylene or hydrogen gas that ows into directly to said focal A whereby to produce l not only to its annular rearward side to its annular frontward side, are a pluralityfof holes 26 through which gas may dow from the annular space 22 into the annular space 27, between the outer surfaces ofj'the portions 10 and 11 and the inner surface of the sleeve 23, and thence through the minute apertures 13 to the focal point of combustion.

Projecting in a sidewise direction from the sleeve 21, in parallel with the nipple 1f? is an integral screw-threaded nipple 28 that is provided with a that connect-s with the annular space 22.

Connected to the nipple 28 by a union 30 is a conduit pipe 31 that may be extended to connect with a source of combustible gas, as acetylene gas or hydrogen gas under pressure. Suitably supported in a spaced concentric position within the conduit pipe 31 .is a smaller pipe 32 which terminates -in a constricted nozzle 33 at a point slightly spaced from the. entrance to the passageway 29 of the nipple 28, which pipe 32 may be extended vto connect with a source of oxygen gas or steam under pressure, whereby said oxygen gas or steam may issue from the form of a jet to mix with the passageway 29 from the space between the concentrically disposed pipes 31 and 32. burner embodying my invention in the manner ereinbefore described, may be utilized to cut througha plate, a bar, or other mass of metal by melting away portions of such metal along the line of the cut. by connecting the pipes 20 and 32 by flexible hose to a sourceof oxygen gas ld connecting the pipe 31 by another ilexiwhereupon the oxygen ,gas from the pipe-32 and the acetylene or hydrogen gas from the pipe 31 will inpassageway 29 and How termingle within the therefrom into the annular space 22 and -thence through the holes 26' of the flange 25 into the annular space 27 and thence through the minute apertures 13 to the focal point of and there be ignited, while thel combustion, oxygen gas from the pipe 20 will How through the passageway 18 into the passageway 15 and thence through the constricted outlet end of said passageway 15 point of combustion, thus to accelerate the combustion of the mixture that issues from the apertures 13 a dame of extremely lugh temperature that will quickly melt steel and other metals. e `f t The Harige 25 and the collar 12, being perforated with small h'oles, serve as a bae, prevent the dame from striking back into the burner, but .they also aid in causing the oxygen and acetylene gases more passageway 29 through it .crooked pipe 43 and a under pressure with respect to the hose toga source of acetylene or hydro- Vgen gas under pressure,

made.

Learner in Figs. 1, 2 and 3, in mode of operation,

but which differs therefrom inxthe construction and arrangement olicertain parts thereof.

1n Fig. 4 the parts 34 and 35, which correspond respectively to parts 23 and 21 of Fig. 1, are made to be integral with each other instead of being made in separate pieces, and the part 36, which corresponds to the part 4 of Fig. 1, is provided with a nipple on which is a removable cap 37 in place of a plug 16 of Fig. 1, said cap 37 being interchangeable with a unionI 38, which corresponds to the union 19 which union 38 is removably connected with a nipple 39 that corresponds to thenipple 17 of Fig. 1.

A nipple 40 corresponds to the nipple 28 of Fig. 1 and in'Fig. 4 said nipple 40 is shown as connected directly with the pipe 31'by a union 41' that corresponds to the unionv 30 of Fig. 1, while in Fig. 5 said nipple 40 is shown as being connected to said pipe 31 bv a union 42, a short piece` of union 44 whichcorresponds to the union 30 'of Fig. 1.

Thus modified. my burner may be changed arrangement of its parts so that its flame may be directed. asmay be of Fig. 1, andv .my burner which is like required under different conditions of operavfrom the annular space 27 into the passageway 18 when said gas burner is in operation thereby avoidmg any back lire which 1s a common occurren e in burners heretofore What l' claim is: Y A gas burner of the class described, which embodies a hollow bodv portion having two externally screw-threaded nipples on one of its end portions, said nipples having like screw-threads and being disposed with their axes at right angles to each other and each having an inlet passageway that extends therethroughto the interior space of said body portion, the other end portion of said body portion having an integral tubular portion extending therefrom throughwhich gaseous fluid may flow from said interior' space to a point of combustion; a largertubular portion connected to said other end portion of said body portion and disposed ooncentrically to surround the integral tubular portion of said body portion to form an annular' space therebetween, said larger tubular portion bein provided with an externally screw-threa ed integral nipple. that projects in a sidewise direction therefrom at a point near said body portion and throughwhich nipple extends an inlet passageway.
